EASY GEOMETRY**
what is the measure of the angle shown.​

The area of the computer monitor display is approximately 0.103 square meters, with three significant figures.

The area of the monitor display in square meters is found by converting the measurements from inches to meters and then calculate the area.

The conversion factor from inches to meters is 0.0254 meters per inch.

Width in meters = 14.60 inches * 0.0254 meters/inch

Height in meters = 10.95 inches * 0.0254 meters/inch

Area = Width in meters * Height in meters

We calculate the area:

Width in meters = 14.60 inches * 0.0254 meters/inch = 0.37084 meters

Height in meters = 10.95 inches * 0.0254 meters/inch = 0.27813 meters

Area = 0.37084 meters * 0.27813 meters = 0.1030881672 square meters

Now, we determine the number of significant figures.

The measurements provided have four significant figures (14.60 and 10.95). However, in the final answer, we should retain the least number of significant figures from the original measurements, which is three (10.95). Therefore, the answer should have three significant figures.

Thus, the area of the monitor display in square meters is approximately 0.103 square meters, with three significant figures.

Answer: 85.25

Step-by-step explanation:

The maximum output of the roll crusher in tons per hour for material less than 1 in. is 40 tons per hour. The amount of the roll crusher output in the range of 1 in. to ½ in. is 20 tons per hour, and the amount less than ½ in. is 10 tons per hour.

To determine the maximum output of the roll crusher, we need to consider the size reduction process and the efficiency of the screen.

Maximum Output of the Roll Crusher: The jaw crusher has a 2½ in. opening, and the screen has 1½-in. openings. Therefore, the maximum size of the material entering the roll crusher is 1½ in. Since the roll crusher is set at 1½ in., it can effectively crush the material to a size less than 1 in. without any recycle of oversize material.

The efficiency of the screen is given as 85%, which means that 85% of the material passing through the jaw crusher will pass through the screen and the remaining 15% will go to the roll crusher.

The maximum output of the roll crusher can be calculated as follows: Maximum Output = (Output from Jaw Crusher) x (Efficiency of Screen) = (40 in. x 22 in.) x (85%) = 880 in.^2 x 0.85 = 748 in.^2

Since the roll crusher is set at 1½ in., the maximum output in tons per hour can be calculated using the following formula: Maximum Output (tons per hour) = Maximum Output (in.^2) x Roll Crusher Setting (in.) x Roll Crusher Efficiency (tons per in.^2) = 748 in.^2 x 1.5 in. x 40 tons per in.^2 = 44,880 tons per hour ≈ 40 tons per hour

Amount of Roll Crusher Output: To determine the amount of roll crusher output in the range of 1 in. to ½ in. and less than ½ in., we need to consider the size reduction process and the size of the roll crusher setting.

Since the roll crusher is set at 1½ in., the amount of roll crusher output in the range of 1 in. to ½ in. can be calculated as follows: Amount in Range (1 in. to ½ in.) = Maximum Output (tons per hour) x Roll Crusher Setting Range Efficiency = 40 tons per hour x (1 - 0.85) = 40 tons per hour x 0.15 = 6 tons per hour

The amount of roll crusher output less than ½ in. can be calculated as follows: Amount less than ½ in. = Maximum Output (tons per hour) x (1 - Roll Crusher Setting Range Efficiency) = 40 tons per hour x (1 - 0) = 40 tons per hour

The maximum output of the roll crusher in tons per hour for material less than 1 in. is 40 tons per hour. The amount of the roll crusher output in the range of 1 in. to ½ in. is 6 tons per hour, and the amount less than ½ in. is 40 tons per hour.

The time study analyst should account for at least 55 observations in order to calculate the mean time per item with a 95.5% confidence level and a 0.4 minute margin of error.

We can use the sample size calculation formula in a confidence interval to get the number of observations required for a time study with the specified parameters:

\(n = (Z * \sigma / E)^2\)

Where:

n = sample size

Z = The target confidence level's Z-score (95.5% translates to roughly 1.96)

σ = procedure standard variation (1.5 minutes per piece)

E = margin of error (0.4 minutes)

Plugging in the values, we can calculate the sample size:

\(n = (1.96 * 1.5 / 0.4)^2\)

\(n = (2.94 / 0.4)^2\)

\(n = 7.35^2\)

n ≈ 54.02

We round up the sample size to the next whole number because we can't have a portion of an observation:

n = 55

Therefore, the time study analyst should prepare for at least 55 observations to estimate the mean time per item with a margin of error of 0.4 minutes and a confidence level of 95.5%.

(i) The probability of both events A and B happening, P(A and B), is 0.12. (ii) The probability of either event A or event B happening, P (A or B), is 0.58.

First, let's define what it means for events to be independent. Two events A and B are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. In other words, the probability of both events occurring together is equal to the product of their individual probabilities: P (A and B) = P(A) x P(B).

Using this formula, we can find the probability of both events occurring together:
P (A and B) = P (A) x P(B) = 0.3 x 0.4 = 0.12

Now let's find the probability of either event occurring. We can use the formula P (A or B) = P (A) + P(B) - P(A and B).
We already know that P(A) = 0.3 and P(B) = 0.4, and we just found that P (A and B) = 0.12. Plugging those values into the formula, we get:
P (A or B) = 0.3 + 0.4 - 0.12 = 0.58
So, the probability of either event occurring is 0.58.
In summary:
(i) P (A and B) = 0.12
(ii) P (A or B) = 0.58

iq scores have a bell shape distribution with a mean of 100 and standard deviation of 15. 81.855%  of the population has an iq score between 70 and 115

What is z-score?

The z score, also referred to as the standard score, serves to calculate how far each data point place is from its mean. In other words, it calculates x's (data point's) deviation in terms of standard deviations.

Using z tables, you may calculate the proportion of the population that is either below or above the score.

Now, according to the question;

IQ scores follow a normal distribution, with a mean of 100 as well as a standard deviation = 15.

A z score is determined as follows:

z = (x - μ)/σ

μ = mean of the distribution

σ = standard distribution of the sampling.

Calculation for the z score for x = 70 and  115

z= (70-100)/15

= -30/15

=-2

and x=115

z = (115 - 100)/15

= 15/15

z = 1.0

Use z-score table, then likelihood that a randomly chosen person's IQ is more than 115 is,

P( -2 < z < 1)= P(z<1) - P(z< -2)

                   =  0.8413 - 0.02275

                  = 0.81855

Therefore, the percent of the population has an iq between 70and 115 is 81.855%.

Answer:

Step-by-step explanation:

he height of the storage unit is equal to twice its radius (since the diameter is twice the radius), so the height is 2 x 8 = 16 feet.

The storage unit is in the shape of a cylinder, so we can use the formula for the volume of a cylinder, V = πr^2h, where r is the radius and h is the height:

V = π(8^2)(16)

V = π(64)(16)

V = 3,218.69 cubic feet (rounded to two decimal places)

Therefore, the volume of the storage unit is approximately 3,218.69 cubic feet.

Answer:

The indifference point is 50 orders.

Step-by-step explanation:

Giving the following information:

Fundraiser A:

$1.50 for each order places plus $75 as a bonus.

Fundraiser B:

$3.00 for each order placed.

First, we need to structure the fundraisers' formula:

Fundraiser A= 75 + 1.5x

Fundraiser B= 3x

x= number of orders

Now, we equal both formulas and isolate x:

75 + 1.5x = 3x

75/1.5= x

50= x

The indifference point is 50 orders.

Prove:

Fundraiser A= 75 + 1.5*50= $150

Fundraiser B= 3*50= $150

Answer:   \(2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}\)

===========================================================

Explanation:

The first term is \(a_1 = 2\text{x}\) and the common ratio is \(r = \text{x}^3\)

To get the second term, we multiply the first term by that common ratio

\(a_2 = a_1*r = 2\text{x}*\text{x}^3 = 2\text{x}^4\)

Repeat a similar idea for the third term

\(a_3 = a_2*r = 2\text{x}^4*\text{x}^3 = 2\text{x}^{4+3} = 2\text{x}^7\)

and the fourth term is

\(a_4 = a_3*r = 2\text{x}^7*\text{x}^3 = 2\text{x}^{7+3} = 2\text{x}^{10}\)

The fifth term is

\(a_5 = a_4*r = 2\text{x}^{10}*\text{x}^3 = 2\text{x}^{10+3} = 2\text{x}^{13}\)

Something to notice: The exponents of the first five terms are: 1, 4, 7, 10, 13. The sequence of exponents is arithmetic even though the original underlying sequence is geometric.

The reason why the exponent sequence is arithmetic is because we keep multiplying by \(\text{x}^3\), and hence we keep adding 3 to each exponent to get the next exponent.

-----------------------------------------

To summarize, the first five terms are:

\(2\text{x}, \ 2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}\)

We will ignore the first term 2x since your teacher wanted you to find the next four terms after that first term (i.e. term2 through term5).

Step-by-step explanation:

They function by balancing their budgets through a combination of these revenue streams, along with careful budgeting and expenditure management.

Comparing a state without an income tax to one with an income tax, the key differences lie in the tax burden placed on residents and businesses. In the absence of an income tax, individuals in the state without income tax enjoy the benefit of not having a portion of their businesses may find it more attractive to operate in such states due to lower tax obligations. However, these states often compensate for the lack of income tax by imposing higher sales or property taxes.

States without a state income tax, such as Texas, Florida, and Nevada, function by generating revenue from various alternative sources. Sales tax is a major contributor, with higher rates or broader coverage compared to states with an income tax.

Property taxes also play a significant role, as these states tend to rely on this form of taxation to fund local services and public education. Additionally, fees on specific services, licenses, or permits can contribute to the state's revenue stream.

Comparing such a state to one with an income tax, the key differences lie in the tax structure and the burden placed on residents and businesses. In states without an income tax, individuals benefit from not having a portion of their earnings withheld, resulting in potentially higher take-home pay. This can be appealing for professionals and high-income earners. For businesses, the absence of an income tax can make the state a more attractive location for investment and expansion.

However, the lack of an income tax in these states often means higher reliance on sales or property taxes, which can impact residents differently. Sales tax tends to be regressive, affecting lower-income individuals more significantly. Property taxes may be higher to compensate for the revenue lost from the absence of an income tax.

Additionally, the absence of an income tax can result in a greater dependence on other revenue sources, making the state's budget more susceptible to fluctuations in the economy.

Overall, states without a state income tax employ alternative revenue sources and careful budgeting to function. While they offer certain advantages, such as higher take-home pay and potential business incentives, they also impose higher sales or property taxes, potentially impacting residents differently and requiring careful management of their budgetary needs.
